.GASQLJENE-ENGINE.

IE-atented. Dec. 31, 1.

' a citizen of the United States, residing at the casin and one wrist pin.

Logansport, in the county of Cass and State of Indiana, have invented a new and useful lmprovement in a GasolenaEngine, of which the following is a specification.

This invention relates to gasolene engines.

and has for its object an engine of this type in which an increased amount of power may be obtained without a proportionate increase in size, weight, and cost of the engine, and a further object of the invention is to reduce the amount of friction to a minimum by re,- ducing the number of bearings and to also obtain a very light and compact engine. In engines of this kind it is common to have on a four cylinder engine, nine bearings andon a six cylinder engine, thirteen bearings. l have reduced this number to five and seven respectively, and this not only reduces the amount of friction but also enables me to shorten the length of the casings and of the drive shaft and thereby obtain a very light engine for the number of cylinders used.

The invention consists of the novel features of construction, hereinafter fully described, pointed out in the claims and shown in the accompanying drawings, in which,

Figure 1 is a vertical sectional view taken longitudinally through one set ofoppositely disposed cylinders, and transverse through Fig. 2 is a section on t e line 22 of Fi 1. Fi 3 is a section'on the line 3-3 of Fig. 1. Fig. 4 is a section on the line 44. of Fig. 1. Fi 5 is a diagrammatic view illustrating the re ative the casing and through a ositions of the pistons in the res ective cylinders, and the relative angle 0 the crank portions of the driving shaft. Fig. 6 is a detail sectional view through a small portion of 'de sleeve illustrating the construction 0 a valve moving mechanism parts being detached. Fig. 7 is a longitudinal section through a coil spring and attached parts, the parts being shown in elevation in Flg. 6.

In these drawings I have illustrated my invention as ap lied to a four cylinder engine, altho h it w be understood that it can be applie to any multiple of a twocylinder englne which may be desired by the addition of the extra cylinders and the parts necessary to coact with them.

. whic In these drawings, A re resents a casing which is provided with a etached orse arate bottom portion A, and the casing is I provided upon opposite sides with arms, A

by means of which it can be mounted or secured in place.

Upon the casing A are mounted two sets of cylinders C the cylinders of each set being arranged out of the perpendicular at an angle of about thirty-two degrees and the two sets being oppositely arranged. Each cylinder is providedwith piston C and is surrounded by a water jacket C and is also provided with an exhaust nozzle C and each water jacket is provided with a drain pipe C and a supply pipe C Passing longitudinally throughthe casing A is a driving or power shaft B, provided in the case of a four cylinder engine with two, cranked portions, each of which hasia pin B. A fluid vapor pipe D s'u plies each of the four cylinders by means of our branch pipes D. These fluid vapor inlet pipes D open into a chamber D formed upon one side of the cylinder pro er and this chamber opens into an igniting c amber D formed at the upper endsof the cylinders and communicatmg with the clearance space. A suitable igniting or pin D ignites the vapor passed into the chambers D Commumcation between the chambers D and D is controlled by a suitable check valve E which cooperates. with a suitable valve seat formed between said chambers.

To the iston C of one set of cylinders C are ivota y connected pitman rods F, and

to t e pistons C of the other set of cylinders are pivotally connected itman rods F,

are slotted at their lower ends as shown at F and a pitman F is pivotally connected to each of the wrist nns B within the bifurcation F of one of the rods F, so

that to each wrist pin B are. ivoted two pitmen of one of the sets-of cy ders C.

ltwill be obvious therefore that as the cylinders C are arranged in o positely disposed sets the same holds true 0? the pistons. To distinguish more clearly between the piston rods of one set are desi nated by the referenceletter F and of the ot er set by the reference letter F, the construction being the same. The-wrist pins B are also dise posed atangles of ninety degrees apart and these sets the various pistons will therefore occupy at v the ot any-given time different positions in their various cylinders.

As shown in Fig. 5 as' one of the pistons is upon the point of commencing a stroke'upwardly, in a cylinder of oneset, a piston of' an. opplositely arranged cylinder, that is, .-in

er set, has made one fourth of the stroke, the adjacent piston G has made onehalf of a stroke and the istonC' in the remaining cylinder of the ast mentioned set, has completed a stroke, and it will be also observed from said diagram that as a piston to which is connected a pitman rod F is ending its stroke, a second piston to which is the pipes D into the igniting chambers D G carries two eccentrics H, which are the following mechanism is employed :A shaft G is arranged above and parallel to the shaft B and there is mounted upon this shaft a gear wheel G which meshes with a gear wheel G carried by the shaft B, the gear wheel G being twice the size of the gear wheel G and making one revolution to two revolutions of the gear wheel G. The shaft rovided with an eccentric stra H and a b ock H, the block H forming the upper half of the strap. A suitable casting J is' formed upon the casing A between the two sets of c linders and in this casting which is suitably cutout are arranged a plurality of guide sleeves J one for each valve E and within the sleeves J are loosely placed close coil sprin s J? which are connected at their upper en s to the valve stems J and at their lower ends to links J which are pivotally connected to ends of the blocks H In Figs, 6 ,and 7 I have shown the details of construction of these parts and it will be noted that the spring J has :1, pl J F threaded into its u per end and into t 's plug is threaded the iower end of the valve-stein J a suitable nut being used to lock the same in lace. the lower end of the spring J z and in the bifurcation of the lug J is pivoted the upper end of one ofthe J It will be understood that two of the links are connectedto each of the blocks H and to opposite ends of the said block, and that they actuate valves E stems, and links Afbifurcated plug J is threaded into in opposing cylinders. As the eccentric H rotates'it will lift the ends of the blockH alternately, and it will also be noted that the sleeves J are arranged parallel to the cilimby the block H aided by t e spring, as 'the tendency of the springs J are to force the block H down upon the periphery of the eccentric H.

' Having thus fully described my invention,

what I claim as new and desire to secure by Letters Patent, is:

1 The combination with an engine having cylinders arranged in oppositely disposed sets, pistons in said cylinders, a power shaft, piston rods connected to said power shaft, a parallel shaft driven from the power shaft, vaive chambers carried by the cylinders, valves in said chambers, eccentrics on .the

second mentioned shaft, blocks on the eccentrics, straps holding the blocks in place, and means for pivotally connecting two valves of oppositely disposed cylinders to the same block. I i

2. In a multi-cylinder engine, cylinders arranged in oppositely disposed sets, pistons,

piston rods, a common crank shaft, a second shaft, driven from the crank shaft, eccentrics thereon, blocks on the eccentrics, valve casings carried by the cylinders, valves therein, va ve stems, springs connected to the valve ivotally connecting the springs to the blocl s, valves of opposite sets being connected to the same.

3. A valve mechanism for multi-cylinder engines comprising an eccentric, a block fit ting-thereon,- a strap connected to the corners of the block, valves, said valves being carried by the oppositely disposed cylinders, valve stems, closed coiled springs connected to the outer'end of the stems and links each pivotally connected atone end to' a spring and at the opposite end to one of the'remaining corners of the blocks.
